LS4 Performance - spark plugs

anyone heard of these or ever used them?

another thread someplace about them. The consensus is that they are very efficient. Efficient at separating you, unnecessarily, from your money.

You'll never get your moneys worth outa those things.

Factories are good for 100k. I'm using Bosch IR Fusion, but I got a good deal on them.

I've had very good luck with NGK V-Power plugs.

They work awesome, and they are cheap, about $2 each. I use them in my 600+ hp turbo mustang, my procharged denali, and my girlfreinds '02 Mustang GT before and after I added a Kenne Bell supercharger. I'm about to pick up a set of the TR5's (stock #2238) for my GXP as well.

Lets face it, unless you are going from really old plugs (100k+miles) to brand new plugs, you are not going to notice a difference in performance. So if you aren't going to notice it, why waste the money? You would probably get more power from an eBay electric supercharger LOL. Save your money for something worthwhile like an exhaust or a tune. If you really want a better spark, spend the money on an MSD box.
